The Challenge of Champions was an exhibition tennis tournament. Featuring a roster of 8 invited players, it was not recognized by the sport's main sanctioning bodies, but was one of the most lucrative and better regarded non-tour events. Beginning in 1980, it was organized by Canadian company Concert Productions International, which the following year launched a sister event called the Molson Challenge in Toronto.[1] The tournament was discontinued after the 1989 edition.
